Depth-dependent displacement modulated indentation in oriented polypropylene

The mechanical properties of kink bands which develop during micro-indentation testing of oriented polypropylene have been analyzed in terms of a viscoelastic model. Stress relaxation and dynamic mechanical measurements have interpreted in terms of the geometric softening effects within the constrai...

More Information
Summary:The mechanical properties of kink bands which develop during micro-indentation testing of oriented polypropylene have been analyzed in terms of a viscoelastic model. Stress relaxation and dynamic mechanical measurements have interpreted in terms of the geometric softening effects within the constrained region of the kink band.
